Lab experiments are controlled experiments, although you can perform a controlled experiment outside of a lab setting! In a controlled experiment, you compare an experimental group with a control group. Ideally, these two groups are identical except for one variable, the independent variable.
A variable that is kept constant during a controlled experiment. control group In an experiment, the group that is not exposed to the treatment; contrasts with the experimental group and serves as a comparison for evaluating the effect of the treatment.

All of the other variables, such as the temperature, should be kept consistent and are designated as controlled variables. Experiments typically have many controlled variables, but only one experimental variable. Experimental variables are crucial to the scientific process; without them, the experiment is pointless.
1.variable anything that can change in research (p.27) 2.theory - a broad idea or set of closely related ideas that attempts to explain observations and to make predictions about future observations - ambiguity: do NOT confuse with hypothesis, which is a smaller and testable component of a theory (proving a hypothesis helps prove a theory) (p.27)
The dependent variable is the variable that is being measured or tested in an experiment. For example, in a study looking at how tutoring impacts test scores, the dependent variable would be the participants' test scores, since that is what is being measured.
Dependent Variable:...the variable that the experimenter hypothesizes is "affected by," or "related to," the independent variable. It is the "outcome" or "effect" variable, usually a measure of the subjects' performance resulting from changes in the independent variable. In the example, above, the dependent variable might be the number of nonsense syllab...
